In reference to the patent: US6622464
The description from this patent reads:
The applicants have discovered that the placement of the prior art pivot axis 192 and the geometry of bedbar 186 relative to reel 22 causes the front edge of bedknife 24 to also move rearwardly relative to reel 22 as it moves upwardly... As this happens, the Applicants further discovered that the cutting reel would become more aggressive in its cutting action...
Is there a way for me to find what prior art was being referenced in this paragraph?
